On Syria and Iran, it seems that Saudi Arabia is more hawkish than Netanyahu's Israel (or AIPAC et. al. for that matter,) and very upset with the Obama administration's stances:

The Saudis have made no secret of their displeasure over U.S. President Barack Obama's decision to call off his cruise missiles and negotiate a deal with Russia to work to dismantle Syria's chemical weapons program. On October 7, Saudi Arabia's Foreign Minister Saud al Faisal abruptly cancelled plans to deliver his government address to the U.N. General Assembly; the move was widely viewed as a response to the Security Council's endorsement of the Syrian chemical weapons deal. "They saw that as a complete capitulation," said one U.N.-based diplomat.

In protest, the Wall Street Journal reported on Tuesday, Saudi Arabia’s intelligence chief announced that Riyadh will dial back  cooperation with Washington to train and equip Syrian rebels. "Our interests increasingly don’t align," a U.S. official told the paper.

A further sign of pique: the Saudis didn't even inform America's top diplomats in New York that they planned to abandon the Security Council. The Saudi protest at the U.N., according to Davidson, constituted a kind of cry for attention, an effort to "shock and wake up their erstwhile allies."

From Riyadh's perspective, the Syrian civil war represents a pivotal front in an existential political and religious struggle for influence in the region, pitting Iran's Shiite rulers against predominantly Sunni Arab rulers. "There is a realization in Riyadh that it is time for the major Arab powers to prepare a response for maintaining order in the Arab world and to counter Iran's expanding infiltrative policies," Nawaf Obaid, a senior fellow at the King Faisal Center for Research and Islamic Studies,  wrote in Al-Monitor. "The kingdom and its regional allies will increase their support to the Syrian rebels and prevent a collapse of collateral nations, such as Lebanon and Jordan. The removal of the tyrannical regime in Damascus is simply too important for the future of the Arabs."
